Celebrate 7-Eleven’s birthday Wednesday with free Slurpees at these locations around Greeley

With temperatures Wednesday expected to hover around 100 degrees, the forecast for the greater Greeley area is long lines in front of 7-Eleven Slurpee machines.

Factor in that Wednesday's date is also 7-11 — known as Free Slurpee Day to those in the know — and you can expect really long lines when the free small drinks are handed out between 11 a.m. and 7 p.m.

The convenience chain reported that about 9 million free Slurpees are given away annually during Free Slurpee Day, which began in 2002 as a way to mark 7-Eleven's birthday.
